Abstract
The utility model discloses a disposable syringe with medicine, which belongs to an invention of a medical syringe. The syringe adopts a plastic injection cylinder, the double-layer structure of a glass inner tube is arranged in the plastic injection cylinder, and the double-layer structure is convenient for injecting medical liquor automatically from the front end and storing medical liquor to avoid the reaction. The front end of the injection cylinder is fixedly installed on a needle stand which is provided with a rubber pad penetrating the needle head inside, inverse side arm-rests at the rear end of the injection cylinder are bevel non-retreat notches, and the inverse side arm-rests are exactly formed in a non-retreat structure corresponding with the push rod and handle slope edge. The utility model is special for single usage, and the advanced development obtains a satisfactory result by a trial.
Description
This utility model relates to a kind of injector for medical purpose, particularly a kind of disposable Syringe with medicine in it.
At present the syringe that uses clinically mostly is medical glass and makes, and front end is the hollow nipple, and airtight insertion rear end is the piston of handle in the injection tube, but and push-and-pull move, for extracting or injection liquid.
In recent years, the syringe that disposable non-toxic plastic is made is the pushing ram of band handle with the piston transformation of the way then, bar head plug-in mounting rubber piston, and it moves absorption or injection liquid nationality in injection tube.
Above-mentioned two kinds of syringes all need the ampoule cervical region of interior powder charge liquid is fractureed in use, can draw medicinal liquid.The glass chip microgranule falls into medicinal liquid in the operation, injects health and jeopardizes health, and medicinal liquid is exposed to and easily causes pollution in the air.Complicated operating process, medical worker's labor intensity is big, inefficiency.Influence the physical and chemical index of biological product such as vaccine during part biological goods fill ampoule heat sealing to a certain extent.
Chinese patent 902051431 discloses a kind of disposable direct injection special ampule, in injection tube, pre-install medicinal liquid, pushing ram made help pull a cart and the equitant double-joint type structure of core tube, but the unsuitable long term store medicinal liquid of the injection tube of plastic material, and medicinal liquid perfusion inconvenience.
The purpose of this utility model is exactly for a kind of disposable Syringe with medicine in it that is suitable for medicinal liquid storage and mechanization fill is provided.
This utility model is by following conceptual design.
This syringe comprise cylindric plastics injection tube and the glue that is inserted on the syringe needle stifled, be that an end band rubber piston, the other end are the pushing ram of coaxial round handle in the injection tube.Plastics injection tube rear portion internal diameter forms an inwall border step less than the front portion, and the anterior flat mouthful of open tight fit of also can packing into just can terminate in the tubular glass inner tube of step, forms double-decker.The advance and retreat that the rubber piston of pushing ram one end can thereupon closely cooperate in glass inner tube move.Anti-limit, injection tube rear end handrail opisthotonos backward is a groove retaining recess, forms corresponding retaining structure with limit, pushing ram handle slope.The anterior airtight installation of injection tube top is the round table-like hollow needle stand of nipple bottom opening, adds rubber cushion in the needle stand, and syringe needle cements in nipple and the needle stand and penetrates rubber cushion.
Insert glass inner tube during application before the injection tube and terminate in the step place, rear portion insertion piston and pushing ram add the needle stand of establishing rubber cushion in the button and fix it, with shutoff injection tube front portion to glass inner tube after prosopyle mechanization liquid drug, the part air is discharged through syringe needle, and it is stifled to add glue again.Hot pressing film package sterilization is standby.
She Ji Syringe with medicine in it can not be appeared again because of handle and injection tube rear end retaining recess form the retaining structure like this, so only be disposable use; Add the needle stand that is stamped rubber cushion behind the prepackage medicinal liquid in glass inner tube, can avoid medicinal liquid to contact the chemical reaction that takes place with working of plastics, flat mouthful the glass inner tube mouth of pipe is broad before the injection tube, is beneficial to the mechanization liquid drug.
Below in conjunction with drawings and Examples it is described this utility model.
Fig. 1 is this utility model vertical profile structural representation.
Fig. 2 compresses the retaining structural representation for needle stand and injection tube clamping.
Fig. 3 is needle stand and injection tube spiro connection structure sketch map.
The plastic cylinder shape injection tube 1 rear portion internal diameter of disposable Syringe with medicine in it is less than the front portion, and border step of inwall formation is opened for anterior flat mouthful, inserts the glass inner tube 2 formation double-deckers that tight fit terminates in step.Pushing ram 3 one end rubber pistons 4 can be advanced and retreat in glass inner tube 2 thereupon and be moved.Anti-limit, injection tube rear end handrail 5 opisthotonos backward is a groove retaining recess 6, and forms corresponding retaining structure with the sloping limit of pushing ram handle 7.The outer silk of injection tube 1 anterior cover forms screw connection structure with the needle stand 8 that overlaps internal thread.Needle stand 8 adds the rubber cushion 10 that butylene glue is made, to have sealing property for the round table-like hollow object of the outstanding nipple 9 in top in the needle stand.Syringe needle 11 cements in nipple 9 and the needle stand 8 and wears rubber cushion 10 thoroughly.Syringe needle 11 most advanced and sophisticated plug-in mounting glue are stifled 12, can avoid like this in the transporting procedures because of extruding pushing ram and handle, and cause overflow of drug fluid.
Another embodiment, needle stand 13 internal orifices also can be processed into fin, form corresponding clamping with injection tube 14 front end grooves and compress the retaining structure.
The sample of making is like this obtained satisfied effect through trying out.
Claims (3)
1. disposable Syringe with medicine in it, comprise garden tubular plastics injection tube and the glue that is inserted on the syringe needle stifled, be an end band rubber piston in the injection tube, the other end is the pushing ram of coaxial garden shape handle, it is characterized in that:
A, plastics injection tube rear portion internal diameter form an inwall border step less than the front portion, open for anterior flat mouthful, and the tight fit of can packing into just can terminate in the tubular glass inner tube of step, the formation double-decker;
The rubber piston of b, pushing ram one end, the advance and retreat that can thereupon closely cooperate in glass inner tube move;
C, anti-limit, injection tube rear end handrail opisthotonos backward are groove retaining recess, form corresponding retaining structure with pushing ram and limit, handle slope;
D, the anterior airtight installation of injection tube top are nipple, and the hollow needle stand of garden platform shape of bottom opening adds rubber cushion in the needle stand, and syringe needle cements in nipple and the needle stand, and penetrates rubber cushion.
2. Syringe with medicine in it according to claim 1 is characterized in that overlapping internal thread, the outer silk of the anterior cover of injection tube, the formation screw connection structure at the bottom of the needle stand.
3. Syringe with medicine in it according to claim 1 is characterized in that the needle stand internal orifice also can be made into fin, constitutes corresponding clamping with the outer front groove of injection tube and compresses the retaining structure.
